所述端子排2包括由导电材料制作的基板21，所述基板21上依次叠合中间板22和顶板23，所述中间板22和所述顶板23通过螺钉可拆卸的连接在所述基板21上。中间板22用于与壳体1内电芯的接线柱固定连接，基板21放置在壳体1上，通过中间板22与电芯固定连接将基板21压在壳体1上，防止基板21在壳体1上滑动。外部接线连接在中间板22与顶板23之间。这样在使用时若外部接线的接头处发黑就能方便的卸下顶板23，不需要对整个混合电池进行更换，因此，混合电池的维护成本低。

中间板22的短边直接插接在另一个电芯(锂电池)的接线柱上，由于中间 板22与铅酸蓄电池的接线柱焊接，因此中间板22的短边能够稳定的插接在锂电池的接线柱上，利用一个中间板22连接两个不同的电芯，方便的实现混合电池与外部电线的连接。
所述顶板23包括相互独立的顶板一和顶板二，所述顶板一和所述顶板二分别可拆卸的固定在所述中间板22上。顶板一和顶板二与中间板22之间构成外部线路连接，外部线缆需要连接时将露出导体的线缆压接在顶板一和顶板二之间，当使用时间过长导致顶板23氧化时则单一拆开顶板23更换，不需要对整个混合电池进行更换，因此，混合电池的维护成本低。
所述顶板一与所述顶板二结构相同，所述顶板一包括基础顶板和设于所述基础顶板233一侧的凸形板231，所述凸形板231的凹陷部分与所述壳体1适配；所述基础顶板233与所述凸形板231上均设有用于与所述中间板22固定的固定孔232。

所述盖体12包括基体121，所述基体121上沿所述基体121的长度方向设有若干注酸孔122，所述注酸孔122与所述容置仓1121连通；注酸孔122用于在铅酸蓄电池维护时将酸液注入铅酸蓄电池中，使用时将注酸孔122封堵。
所述基体121沿长度方向的两端分别设有接线柱孔123，所述接线柱孔123 与所述基体121的侧边之间设有容置槽126，所述容置槽126用于容置所述基板21，所述容置槽126的一侧设有用于固定所述基板21位置的定位台124。铅酸蓄电池的接线柱伸出接线孔，容置槽126用于放置基板21，基板21贴合在定位台124上，便于中间板22与的焊接，焊接后，中间板22将基板21压在容置槽126内，避免基板21滑动。
所述容置槽126的槽底设有若干凸台125，基板21放置在所述凸台125上，所述基板21与所述容置槽126的槽底之间有间隙。基板21与凸台125接触，在基板21与槽底之间形成了间隙，由于每次添加酸液后需要用水清洗残余的酸液，为了避免残留的水锈蚀基板21，因此设置了凸台125，这样残留的水就沿着槽底和基板21之间的间隙流出，不会残留在基板21上，端子排2不易锈蚀，从而延长了端子排2的使用寿命。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
